Here's the paper they reference:

I don't want to dismiss it out of hand, but my best guess is that their "proprietary SARS-CoV-2 binding" test had poor specificity and that these were cross reactions.  However, if this is replicated with validated test with known specificity then it would change our understanding of where and when the virus emerged.  Certainly the Chinese have tried to deflect blame by saying it came from Italy.

And yes, if the virus emerged in Italy in September 2019, then I would expect that it was in the US by October 2019 at the latest.
